Which of the following is an appropriate response to a patient reporting chest pain that radiates to the arm?

The appropriate response to a patient reporting chest pain that radiates to the arm is critical because it may indicate a serious condition such as a myocardial infarction (heart attack). Administering oxygen, conducting an ECG, and preparing for potential cardiac intervention is a comprehensive approach that addresses both the immediate and potential underlying causes of the symptoms.

Administering oxygen is important, especially if the patient is showing signs of hypoxia or has difficulty breathing, as it helps ensure adequate tissue oxygenation. Conducting an ECG (electrocardiogram) allows for the assessment of the heart's electrical activity, which is essential in identifying ischemic changes or arrhythmias that may be indicative of cardiac issues. Preparing for potential cardiac intervention is crucial as it means that the paramedic is ready to respond to what could be a life-threatening condition.

This multifaceted strategy ensures that the patient receives timely and appropriate care, potentially mitigating complications associated with cardiac emergencies. It also aligns with the protocols and guidelines typically followed by emergency medical personnel when dealing with suspected cardiac events.
